text: Nervana is an investigational V construct that knocks down the expression of protein kinase C gamma (PKCγ) known to be associated with neuropathic pain and morphine tolerance.
  Two conserved PKCγ sequences across all key model species and humans have been identified, and both single and double DNA cassettes are designed. In vitro, the expression of PKCγ was silenced by 80%. When similar DDRNAI constructs were delivered intrathecally using a lentiviral vector, pain relief in a neuropathic-rat model was demonstrated.
